simpleavr 399 Posted June 7, 2013 Share Posted June 7, 2013 So what have you been doing with your Educational BoosterPack lately This is based on the fix_fft code that's been floating around for many years. I tried both 16 bit and 8 bit, currently fixed to 8 bit as I see no difference for my needs (i.e. limited precision, range), I would invest in a good pre-amp for better results. Things to do More precision timing to achieve the frequency band I want. Better front-end, currently using 1/2 LM258. Adopt non-linear horizontal scale, currently linear scale at about 800Hz...1.6Khz, 2.4KHz, 3.2Khz.... Adopt logarithm amplitude to make the bars make sense to your eyes. Add / enhance effects like attack / retreat rate. Add dynamic sampling / scaling to input signals. bluehash, xv4y, oPossum and 10 others 13 Quote Link to post Share on other sites
